摘　　要：TiO_(2)具有化学性质稳定、无毒、比表面积大、结构可控等优点,在太阳能电池、生物传感器、光催化制氢等领域具有广阔的应用前景。然而,TiO_(2)的高带隙(3.2 eV)限制其只能吸收紫外光,且电子-空穴对复合速率较快,导致TiO_(2)表现出较低的光催化活性。通过结构调控及负载改性等可以优化TiO_(2)纳米材料的光催化反应活性,以TiO_(2)纳米管结构为例,综述了不同改性方法,如浸渍法、电化学沉积法、光化学沉积法等对TiO_(2)纳米管结构及性能的影响,并对其未来的研究方向进行了展望。TiO_(2)has the advantages of stable chemical properties,non-toxic,large specific surface area and controllable structure,and has broad application prospects in solar cells,biosensors,photocatalytic hydrogen production and other fields.However,TiO_(2)can only absorb ultraviolet light due to its high band gap(3.2 eV),and the electron-hole pair recombination rate is fast,resulting in low photocatalytic activity.The photocatalytic activity of TiO_(2)nanomaterials can be optimized through structural regulation and load modification,TiO_(2)nanotube structure wastaken as an example,the effects of different modification methods,such as impregnation,electrochemical deposition and photochemical deposition,on the structure and properties of TiO_(2)nanotubes were reviewed,and the future research direction was prospected.
